Application filed December 6, 1923. Serial No. 678,879.

T all whom t may concern:

Be it known that I, JOHN KosAniK, a citizen of Czechoslovakia., residingat Avella, in the' county of lWashington and State of Pennsylvania, haveinvented certain new and useful Improvements in Auxiliary Brakes forAutomobiles, of which the following is a specification. y

This invention relates to certain new and useful in'iprovements inauxiliary brakes for automobiles and has particular reference to thattype of brake adapted for engagement with the ground and operating toelevate the rear drive wheel from engagement with the ground. Y

The primary object of the invention is to provide an auxiliary brake forautomobiles wherein a pair of cooperating brake arms having groundengaging `feet is associated with each rear drive wheel for insuring thebraking of the automobile and especially adapted for use when theautomobile is at rest.

'llVith the above and other objects in view as the nature of theinvention is better understood, the same consists of the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a fragmentary side elevational view of the rear end of anautmobile showing the improved auxiliary brakes in their elevatedinoperative position, y

Figure 2 is a longitudinal sectional View taken on line LII-H of Fig. 3showing the auxiliary brakes lowered to their ground engaging operativepositions,

Figure 3 is a fragmentary top plan view showing the auxiliary brakeselevated and the devices for operating the same,

Figure 4 is a longitudinal sectional view taken on line IV--IV of Fig.3,

Figure 5 is a fragmentary detail View, partly in section of one of thebrake arms,

Figure 6 is a detail sectional view of a modified form. of brake armrshowing a wooden core having a metallic sheet covering, and

Figure 7 is a fragmentary elevational view of another form of auxiliarybrake arm.

Referring! more in detail to the accom'- panying drawings, a portion ofan auto'moM bile frame is illustrated, such as a side frame' bar 1, therear axle housing2, vdifferential case 3 and rearsupporting wheels thaving the usualbrake 'drums 5 associated with the opposite ends of theaxle in the housing V2.

As shown more clearly in Fig. 2, ahanger plate G depends from the sideframe bar 1 and ournalled'transversely of the automobile fame in thelower endV of the oppositely positioned hanger plates 6 is a pair ofrods 7 and 8. The journalled rods 7 and Sare bent intermediate theirends as at 9 to clear the differential housing 3. CooperatingVoppositely curved brake arms 10 are fixed to the ends of the shafts 7and 8 outwardly of the frame bars 1, each arm carrying a right angularlydirected brake shoe 11 traversing the wheel 4 as shown in Fig. 3, thebrake slices 11 being connected to the arms 10, preferably by the typeof joint 12 shown in Fig. 5. To facilitate proper gripping of the roadby the brake shoes 11, the lower faces thereoffare serrated as at 13.

The rods 7 and Sare caused to rotate in unison by the gears 14 securedto said rods andy meshing with each other, the operating mechanism beingconnected to the forwardly positioned shaft 8 and including an arln 15having a relatively long link rod connection 16 with the brake lever 17,the upper handle end 1S of which moves over the segment 19 to beretained in adjusted positions by the tensioned latchrod 20.

lith the auxiliary brake arms 10 -in their elevated inoperativepositions shown in Fig. 1 the handle end 18k of the brake lever is rearwardly positioned as shown by full lines in Fig. 4, and when the handlelever 18 is forwardly shifted to the dot and dash line position 18a, thetwo shafts 7 and 8 are -aused to be rotated by their gear connections14. with a consequent lowering of the arms l() and the brake shoes 11into engagement with the ground 21 as shown in Fig. 2, the brake shoesllfbeing positioned beneath the wheel 4t and causing a slight elevationthereof to insure proper braking of the automobile. will release theauxiliary brake arm and the wheels 4t will be lowered upon the ground.

If desired, the type of brake shoe illustrated in Fig. 6 may be employedwherein the shoe is formed of wood 22 and hasv a 'sheet metal covering23Fi'1- 7 showin a further modification of t 'e' rake s 0e Reversemovement' of the lever 17 Wherein the shoe l12L is in direct alinementWith the brake arm l() yand engages the ground laterally of the Wheel4C.

While there are herein shown and described the preferred/embdiments ofthe present inieiition, it is nevertheless to be understood that minorchanges may be made therein Without departing from the spirit and scopeof the invention as claimed.

What is claimed as new is l. In an auxiliary brake for automobiles, apair of gear connected shafts journaled across the automobile frameadjacent the rear axle housing, brake shoes carried by the ends of theshafts and manually operable means connected to one of the shafts.

2. ln an auxiliary brakefor automobiles, a pair of gear connected shaftsjournaled across the automobile frame adjacent the rear aXle housing,said shafts having arched portions clearing the differential housing,brake shoes carried by the ends of the shafts and manually operablemeans connected to one of the shafts.

3, in an auxiliary brake for automobiles.y a pair of gear connectedshafts iournaled across the automobile frame adjacent the rear axlehousing, said shafts having arched portions clearing the differentialhousing, pairs of oppositely curved arcuate arms sec Vred to theends ofthe shafts, brake shoes 'ied by the outer ends of the arms and .ianuallyoperable means connected to one of the shafts. y new el. ln an auxiliarybrake Vfor automobiles, a pair of gearconnected shafts journaled acrossthe automobile frame adjacent the rear axle housing, said shafts havingarched portions clearing the differential housing, pairs of oppositelycurved arcuate arms secured to the ends of the shafts, brake shoescarried by the outer ends of the arms and manually operable meansconnected 1ro one f the shafts, said bra-ke shoes extending at t to thearms and traversing the n of the Wheels.

ln an auxiliary brake for automobiles., a pair of gear connected shaftsjournaled across the automobile frame adjacent the rear axle housing,said shafts having arched portions clearing the differential housing,pairs of opposiely curve' arcuate arms cured to the ends of the shafts,brake shoes carried by the outer ends of the arms, manoperable meansconnected to one of the s, said brake shoes extending at right 'les tothe arms and traversing the path the Wheels, and hanger plates for themobile frame.

ln testimony whereof I afliX my signature.
